The accelerators complex at Diamond consists of a 100 MeV LINAC, a full energy booster and a 3GeV storage ring with 22 straight sections available for Insertion Devices (IDs) to produce synchrotron light.

The Accelerator Physics Group performs fundamental studies to model, understand and optimise the performance of the Diamond accelerators under a range of operating conditions.

Many aspects of the design and operation of the Diamond machine are particularly challenging, requiring careful machine design and a vast computational effort:

• achieving a small beam emittance
• very high orbit stability
• non-linear beam dynamic optimization for a long electron beam lifetime with numerous small gap IDs
• high current operation.

Diamond is also designed to perform top-up injection schemes (frequent addition of electrons into the storage ring), requiring a careful design of the injector system and beam losses studies.

Studies are performed in close collaboration with the ID group in order to specify the magnetic field quality in the magnets and in the IDs. Implementation of the feedback system, used to damp collective instabilities, is performed in collaboration with the Diagnostics group.
